The Aztecs attack the Spanish and imprison many of Cortes' soldiers.
The Aztecs attacked the Spanish and forced them into a desperate escape from Tenochtitlan. More than 600 Spanish conquistadors (some estimates ran to over 1,000) and thousands of Tlaxcalans died trying to run across a narrow bridge. Cortés retreated back to Tlaxcala, barely making it through an enormous Aztec army. The elemental horror of that night has never been forgotten. It is still called "the Night of Tears" (la Noche Triste).
Cortes attacks Tenochtitlan from three directions at once with 13 new ships. The lake surrounding the city turns red with blood.
15,000 Aztecs die in Cortes' final all-out attack on the city. The new Emperor Cuauhtemoc and his last few supporters are captured by the Spaniards
